We consider transport properties of disordered two-dimensional electron gasesunder high perpendicular magnetic field, focusing in particular on the peaklongitudinal conductivity $\sigma_{xx}^\mathrm{peak}$ at the quantum Hallplateau transition. We use a local conductivity model, valid at temperatureshigh enough such that quantum tunneling is suppressed, taking into account therandom drift motion of the electrons in the disordered potential landscape andinelastic processes provided by electron-phonon scattering. A diagrammaticsolution of this problem is proposed, which leads to a rich interplay ofconduction mechanisms, where classical percolation effects play a prominentrole. The scaling function for $\sigma_{xx}^\mathrm{peak}$ is derived in thehigh temperature limit, which can be used to extract universal criticalexponents of classical percolation from experimental data.
